Abstract

The past and current presence of the Italian freshwater crayfish Austropotamobius fulcisianus in the Farma-Merse basin was surveyed. Historically, the species was present in a few small tributaries on the right side of the mid course of the Fiume Merse (La Gonna and its tributaries Ricerchiaio, Rifregaio, Risanguigno and La Bolza; Le Cataste; Faulle; Macinaia; Sermiglione-Dei Pozzi [Ornate di Tocchi]; Lamabuia-Mulinello). Its past presence in other brooks (Migliorina on the right side; Ricausa and Rifredo on the left side) and in a small stretch of the Merse downstream of the confluence of La Gonna is considered possible but not certain. The current distribution has diminished and is limited to La Gonna and its tributaries Ricerchiaio, Rifregaio, Risanguigno and La Bolza, and outside La Gonna basin to Faulle. The reasons for this decline include habitat destruction due to water abstraction and clearing of riparian vegetation, introduction of nonnative fishes such as Salmo trutta and Oncorhynchus mykiss and illegal fishing. The most urgent measures to protect this species in the Farma-Merse basin include: legal protection of the area of distribution, protection of the habitat, population monitoring and banning the introduction of fishes.
